[0038] In this example, the chip Q1 is a NEW_MD8561-3V3 voltage stabilizing chip. The 5V power supply voltage provided by the second pin of the interface J1 is input into the chip Q1 after being filtered by the fifth filter unit 41, and the chip Q1 converts the 5V voltage into a stable 3.3V voltage output. The second RC unit 42 receives the electrical signal output by the chip Q1 and filters the electrical signal output by the chip Q1. The electrical signal filtered by the second RC unit 42 is used to power the third RC unit 43 and the light sensing unit 44. When the light sensing unit 44 is in a daytime or bright environment, the resistance of the light sensing unit 44 becomes low, and the current thereof increases. At this time, the CDS end outputs a high level signal. When the light sensing unit 44 is in a nighttime or dark environment, the resistance of the light sensing unit 44 becomes high, and the current thereof decreases. At this time, the CDS end outputs a low level. When the main control board receives the low level signal output by the CDS end, the main control board outputs a high level to the first pin of the interface J1, so that the white light lamp control module 2 is turned on. When the main control board receives the high level signal output by the CDS end, the main control board outputs a high level to the fifth pin of the interface J1, so that the infrared lamp control module 1 is turned on. In this way, by adding the light sensing module, the light supplementing lamp module with laser function can switch the infrared lamp control module or the white light lamp control module to be turned on according to different environments.
